Inital velocity of the jet (v) = 24 m/s
final velocity (u) = 0
time taken (t) = 1.6 s
acceleration(a) = (final velocity- inital velocity)/ time
= (0 - 24) /1.6
= -24/ 1.6
= -15
so,
the acceleration was - 15 m/s^2
A decrease in velocity is referred to as deceleration. If car is moving at 30 m/s and stop in 50 m .The value of deceleration is 11.56 ms−2.
<h3>How to calculate deceleration ?</h3>
While acceleration is motion in which an object's speed varies every second, deceleration is motion that causes an object to slow down.
We are aware that acceleration refers to an object's rate of increase in speed, and deceleration refers to an object's rate of decrease in speed. For instance, when we apply the brakes while driving, we benefit from the vehicle's ability to decelerate and slow down.
The Deceleration Formula is the final velocity minus the initial velocity, with a negative sign in the result because the velocity is decreasing, if starting velocity, final velocity, and time taken are given.
velocity of car = 30 m/s
car need to stop in 50m
Deceleration a = v^2 – u^2 / 2s
= 0^2 - 50^2 / 2*30
= 11.56
Deceleration of the care = 11.56 ms−2

Answer:
The entropy of the gas increases
Explanation:
The entropy of an isolated system tends to increase. but this gas gas is not isolated. It has a piston perfoming work on it and it can exchange heat with it's surroundings.
While the system's entropy decreases, the surroundings' entropy increases, and the entropy change of the universe, which is the sum of the entropy changes of the system and the surroundings, will be equal or greater than zero.
Answer:
Warm water, cold air
In the current climate, a rule of thumb is that the ocean surface temperature should be above 26.5 or 27 degrees Celsius, or 80 degrees Fahrenheit, for a hurricane to make. ... Hurricanes are machines whose job is to maneuver heat from the nice and cozy ocean to the cold atmosphere above
Explanation:
The SI unit for velocity and speed is meters per second
